[What sort of stroke requires patient admittance to the hospital? Factors for deciding on hospitalization].

Objective: To study main factors determining medical decision in admitting patients with acute cerebrovascular disease (ACVD).
Patients and Methods: This is an observational and transversal study. We analyze a hospitalary cohort made by all consecutive patients with ACVD coming to Emergency Room to Hospital Universitario de la Princesa during 1 year. Neurologist on call made on his/her own decision to admit the patient to hospital. Clinical and epidemiological characteristics of those patients admitted with those who went home are compared.
Results: 517 patients were studied, 147 had transient ischemic attacks (TIA) and 370 had a stroke, 12.3% TIA and 68.4% stroke patients were hospitalized. Age, Canadian Stroke Scale (CSS) on admission, subtype of stroke, atrial fibrillation and abnormal EKG, old lesions in CT, previous TIA and/or CVD, diminished conscious level, orientation and language, sphincter control and evolution time greater than 48 hours were statistically significative in deciding admission. Logistic regression analysis (84.2% total predictive value) showed independent predictive value in age, CSS, previous CVD and some subtypes of stroke (ischemic non lacunar and hemorrhage).
Conclusions: We hospitalize younger patients, with a worse clinical condition and overall hemorrhagic stroke. The percentage of admissions among TIA patients is low. On the other hand, date, time and physicians-team features do not affect the percentage of admissions.
